Application Situation

The company looked for solutions throughout the industry, but had used Belzona many times in the past. Knowing that we could supply, apply and perform in the most difficult of situations, Belzona were appointed to undertake the repair and protection work.
A key consideration in the selection process was downtime and the client could not afford to have to carry out this process more than once. A wise choice, saving the company additional contractor costs and avoiding further unnecessary applications and downtime
